- made the number of buffers a variable instead of hardcoding to 2
- made the buffer size and the #buffers specifiable from the command line
- added a sleep to the main "playstream" loop so as to not peg the CPU (from Ken Russel)

- modified the build to use the minimal needed jars from j-ogg instead of using
the combined j-ogg-all.jar which was causing problems with other tutorials
- removed the old huge crickets.ogg file and replaced it with broken_glass.ogg

Added support for using JOAL alongside JOGL in JOGLAppletLauncher. If
JOAL classes are detected, will download, install and load JOAL's
native libraries as well as JOGL's. Added NativeLibLoader.disable()
method to JOAL to support this. Added code to JOGLAppletLauncher to
detect if -Dsun.java2d.noddraw=true was missing from
deployment.properties and if so to prompt user about adding it
automatically. Fixed bug in new per-native-library timestamp code.
Refactored JOAL SingleStaticSource demo to make it easier to embed in
an applet.
